To all whmn i may 007006770: 1 trical conductors between the controllingBe It known that we, CIIARLEs F. TAYLOR, mechanism and therecordingInstrument. a resident of Hartford, and FREDERICK J. Brieflystated, the mechanism shown in LAROGK, a resident of East Hartford, inthe the drawings comprises a stylus which is car- 5 county of Hartfordand State of Connecticut, ried on the uniformly advancing minutecitizensof the United States, have invented hand of an ordinary time-clock. Asthis certain new and useful Improvements in Rehand is advanced by theclock-movement its cording Mechanism, of which the following is outerend travels within the zone of an eleca full, clear, and exactspecification. tromagnet, which when energized will pull Io Thisinvention relates to recording mechthe hand against the dial-plate, andthus anism, and more especially to that class cause the stylus topuncture the record-disk thereof whereby the speeds attained,disstationary on said plate.

For instance, if a minute elapses and stylus arecontinuously and constantly from the time one puncture is made until the2 5 changed by the advancement of one of said second puncture takesplace the speed of the members through a chronometrieal device vehiclewould be (for an hour) equal to sixty 7 5 as, for instance, atime-clock. eighths of a mile, or, in other words, seven. and

a base-board 12 is firmly secured. Mounted on this base-board is atime-clock mechanism T, which maybe of any desired construction andwhich comprises a staff 13 for actuating the minute-hand 14. Looselymounted on the staff 13 is a sleeve 15, adapted to receive the quill ofthe hour-hand 16 and operated at a ratio of one to twelve by the usual.gear- Y train (indicated in a general way by 17) and disposed below adial-plate 18, which is supported on the casing 10, as shown in Fig. 3,and has a comparatively small permanent dial 19 for use in connectionwith the hourhand 16. The dial plate 18 is preferably made of wood andsupports on its upper face a stationary but removable record sheet ordisk R, havinga central aperture correspond- 5 ing to the outsidediameter of an annular flange 18, whereby it is properly located on Ithe dial-plate l8. The minute-hand 14 cdnsists in the present instanceof a resilient bar supported on the i staff 13 and advancing therewith,and it has at its-outer end a soft-iron armature 14/, travcling over anannular field-plate 20, which is secured to the top of the casing 10 andserves to inclose a coil of wire 21 within an annular groove or recess22, provided theretor. The ends of the Wire coil 21 are secured totermi-g n-als 23 24, respectively, and when a current 3 of electricityis sent through the coil the holdplate 20 will become magnetized andattract the armature 14, tlfus causing an indicator or stylus S, carriedon the minute-hand 14, to puncture the record-sheet R. It may be 5stated at this time that it is of course immateri-al what the nature ofthe stylus is may he, it being evident that any suitahle marking device,either with or without ink, maybeemg ployed in lieu of thepuncturing-point herein illustrated and described without in any way iaffecting the invention. Means are provided tor varying the resiliencyof the bar 14 and tor locating the armature 14" within the magnetic zoneof the liel d- .g plate 20, these means consisting substantially a of astiff arm 25, secured on the minute-stall 1 1'3 and perforated at itsfree end to receive a screw 26, attached to said bar 14 and having a nut'27 for regulating the position of the minute-hand relatively to the arm25. As above stated, the record-sheet is of sullicient capacity to covertwenty-four hours, I and by referring to Fig. 1 it be seen that 5 therecord-sheet has radial lines dividing the 3 same into sixtyminute-spaces and also a 'spif ral line .9, the outer end of whichbegins :at the i index-line i, disposed opposite the numeral XII of thepermanent dial 1-9. The spiral line 8 indicates the pathof the stylus ISin its revolution around staff 13, each convolution approaching thecenter a predetermined distance, so that the succeeding hours may bereadily distinguished. The first convolution covers the period fromsix1a. m. to seven a.rn., 5

the second from seven a. hi. to eight a. 'm., and so on until the lastconvolution ends again at six a. in, thus giving to the record sheet acapacity of twenty-four hours, each subdivided into minutes.

Any suitable mechanism may be employed end of the screw 31 carries apinion 44) in engagement with a gear 41., which may be :sta-

tionary, but is preferably mounted, for the sake of convenience, on thesleeve of the slowly-moving hour-hand, the organization being such as tocause the .ztylus-slide to. move inward about one-tenth of an inchduring each revolution of the minute-hand. When the slide 36 has reachedlimit of its inward movement, the nut-section's 3.3 will beautomatically disengaged fnom the .31 by engaging a conical portion 45of the screw :31.

The entire thus tar described is mounted on and forms a part of thecasing 10, which is provided with a cover-ring 5510, having a glass 51,which permits a plain view of dial and necordesheet iI-icloses themechanism against injury.

The device whereby the magnet1coil'21 is periodically energized atcompletion of a one-eighth-mile travel of the vehicle is clearlyshown'in Figs. 4 and 5., in which W denotes the vehicle-wheel giounnaledon the vehicle-axle A and carrying a tappet vor striker 60 of ordinaryconstnuction. The switch mechanism is mounted on a bracket 61, securedto the axle A, and comprises a star-wheel :62, secured upon a spindle63, which is journaled in the bracket 61 and care ries a pinion .62 inenga ement with a gear i 63,mounteduponaspin 64.,also

in the bracket 61' and having a pinion 65 :secured thereto. ."lhe 6.5meshes in a gear 66, which is loosely mounted for rotation on thespindle '63 and carries an insulated disk '67., provided with :ametallic strip 68, which constitntes a circuit-maker and serves :as amedium whereby an electric connection is established \once during eachcomplete rotation of the (disk 67 and its gear between a pair ofhrushscontacts 7:071, are normally insulated from each other .on aninsulating-block 72, held on the bracket .61.. The gear 66 and disk :67are prevented from longitudinal displacement on the spindle 63 TOO bymeans of a collar 73, and the ratio of gearing is in the presentinstance such that seventy-two rotations of the thirty-sixinchvehicle-wheel WV, equaling a travel distance of one-eighth mile, willresult in one full rotation of the disk 67, therefore connecting thebrushes 71 at the completion of each eighth mile and closing themagnetcircuit, which comprises brush 70, battery B, terminalv 23, coil21, terminal 24, conductor 24, brush 71, and strip 68.

The actual work performed by our improved recorder and. the significanceof the markings on the record-sheet can be readily ascertained byreferring to Fig. 1, which shows a record of a trip, as follows: Thevehicle started from H at 7.2.0 a. 111. The next nine-minute run to Ishows twelve marks, which means three-fonrths of a minute used for eachmark of one-eighth of a mile and a total distance of one and one-halfmiles traversed between 7.20 and 7.29 a. m. Now if it took three-fourthsof a minute to run oneeighth of a mile, as the record-sheet plainlyshows, it would take at the same speed six minutes to run one mile, sothat we find that the vehicle ran at a speed of ten miles per hourbetween 7.20 and 7.29 a. m. and traversed a distance of one and one-halfmiles. Between 7.29 and 7.35 a. 111., a period of six minutes between Iand K, we find sixteen marks, equaling a distance of two miles andshowing a speed of one-eighth of a mile for each three-eighths of aminute, or a twentymile rate. Between K and L the time consumed wasthirty minutes, (from7 .35 to 8.05.) Twelve marks mean a distance of oneand one-half miles traversed, two and one-half minutes for eachone-eighth of a mile or a speed rate of three miles per hour. From L toM it took from 8.05 to 8.08 a. m., three minutes, to accomplish fourone-eighths miles at three-fourths of a minute each, showing aspeed-rate of ten miles per hour. In a similar manner the distance ofonefourth of a mile from M to N was covered between 8.08 and 8.09% a.m., equal to one and one-fourth minutes at a speed rate of twelve milesper hour. From N to O the distance is one-half mile, covered, in one andone-half minutes at the rate of twenty miles. From 0 to P it took sevenminutes to travel three and one-half miles at a speed of thirty milesper hour. From P to Q is a distance of one and one-half miles, coveredin six minutes at a '[ifteenanile rate. From Q to R nine minutes wereconsumed in traversing three miles at a twenty-mile rate. From R to T isa distance of two miles, covered at a tenmile rate in twelve minutes,and from T to U it took twenty-nine and three-fourths minutes to travelone and one-half miles at a speed rate of three miles per hour, thetotal distance from the starting-point H being seventeen andthreefourths miles, and the time consumedwas from? .20 to 9.143;, aperiod of one hour and fifty-four and one-half minutes.

From the foregoing it is evident that our improved recording devicepreserves an accurate account of the performance of a vehicle during anyone day, regarding the distances traveled between given points, thespeed attained, and also the time of the day when the occurrences tookplace.

Having thus described our invention,what we claim is 1. The combination,with an electric circuit comprising an electromagnet, a recordsheet, amarking device cooperative therewith and having an armature, and a timemechanism for advancing said marking device at a uniform rate of speed;of a rotatable wheel; and means for closing said circuit and foractuating said marking device upon the completion of a predeterminedmovement of said wheel.
